SECTION 4: First aid measures
4.1.
Description of first aid measures
First-aid measures after inhalation
: Remove victim to uncontaminated area wearing self contained breathing apparatus. Keep
victim warm and rested. Call a doctor. Apply artificial respiration if breathing stopped.
First-aid measures after skin contact
: In case of frostbite spray with water for at least 15 minutes. Apply a sterile dressing. Obtain
medical assistance. For exposure to liquid, immediately warm frostbite area with warm water
not to exceed 105°F (41°C). Water temperature should be tolerable to normal skin. Maintain
skin warming for at least 15 minutes or until normal coloring and sensation have returned to the
affected area. In case of massive exposure, remove clothing while showering with warm water.
Seek medical evaluation and treatment as soon as possible.
First-aid measures after eye contact
: Immediately flush eyes thoroughly with water for at least 15 minutes. Hold the eyelids open and
away from the eyeballs to ensure that all surfaces are flushed thoroughly. Contact an
ophthalmologist immediately.
First-aid measures after ingestion
: Ingestion is not considered a potential route of exposure.

Advice for firefighters
Firefighting instructions
: Evacuate all personnel from the danger area. Use self-contained breathing apparatus (SCBA)
and protective clothing. Immediately cool containers with water from maximum distance. Stop
flow of gas if safe to do so, while continuing cooling water spray. Remove ignition sources if
safe to do so. Remove containers from area of fire if safe to do so. On-site fire brigades must
comply with OSHA 29 CFR 1910.156 and applicable standards under 29 CFR 1910 Subpart
L—Fire Protection.
Protection during firefighting
: Compressed gas: asphyxiant. Suffocation hazard by lack of oxygen.
Special protective equipment for fire fighters
: Use self-contained breathing apparatus. Standard protective clothing and equipment (Self
Contained Breathing Apparatus) for fire fighters.
Specific methods
: Use fire control measures appropriate for the surrounding fire. Exposure to fire and heat
radiation may cause gas containers to rupture. Cool endangered containers with water spray jet
from a protected position. Prevent water used in emergency cases from entering sewers and
drainage systems.
Stop flow of product if safe to do so.
Use water spray or fog to knock down fire fumes if possible.
SECTION 6: Accidental release measures
6.1.
Personal precautions, protective equipment and emergency procedures
General measures
EN (English US)
: Evacuate area. Ensure adequate air ventilation. Prevent from entering sewers, basements and
workpits, or any place where its accumulation can be dangerous. Monitor concentration of
released product. Try to stop release.

Precautions for safe handling
Precautions for safe handling
7.2.
: Wear leather safety gloves and safety shoes when handling cylinders. Protect cylinders from
physical damage; do not drag, roll, slide or drop. While moving cylinder, always keep in place
removable valve cover. Never attempt to lift a cylinder by its cap; the cap is intended solely to
protect the valve. When moving cylinders, even for short distances, use a cart (trolley, hand
truck, etc.) designed to transport cylinders. Never insert an object (e.g., wrench, screwdriver,
pry bar) into cap openings; doing so may damage the valve and cause a leak. Use an
adjustable strap wrench to remove over-tight or rusted caps. Slowly open the valve. If the
valve is hard to open, discontinue use and contact your supplier. Close the container valve
after each use; keep closed even when empty. Never apply flame or localized heat directly to
any part of the container. High temperatures may damage the container and could cause the
pressure relief device to fail prematurely, venting the container contents. For other precautions
in using this product, see section 16.
Conditions for safe storage, including any incompatibilities
Storage conditions
: Store in a cool, well-ventilated place. Store and use with adequate ventilation. Store only
where temperature will not exceed 125°F (52°C). Firmly secure containers upright to keep
them from falling or being knocked over. Install valve protection cap, if provided, firmly in place
by hand. Store full and empty containers separately. Use a first-in, first-out inventory system
to prevent storing full containers for long periods.
OTHER PRECAUTIONS FOR HANDLING, STORAGE, AND USE: When handling product
under pressure, use piping and equipment adequately designed to withstand the pressures to
be encountered. Never work on a pressurized system. Use a back flow preventive device in
the piping. Gases can cause rapid suffocation because of oxygen deficiency; store and use
with adequate ventilation. If a leak occurs, close the container valve and blow down the system
in a safe and environmentally correct manner in compliance with all international,
federal/national, state/provincial, and local laws; then repair the leak. Never place a container
where it may become part of an electrical circuit.

checked for leakages. Provide adequate general and local exhaust ventilation. Ensure
exposure is below occupational exposure limits (where available).
